I've never had problems with condenser mics. Granted, I've been doing voice acting and music recording for many years, so I understand the potential drawbacks. Still, I would rather have more editing to do in post and have great audio than use a dynamic mic and have (very slightly) diminished quality.
Qualifications for part D include having Part A, Part B and/or Part C. If I am eligible when does it become effective? Medicare becomes effective when you turn 65, the first day of that month. For example, if you turn 65 on October 20th, 2009 your Medicare coverage would have become effective October 1st, 2009. There are also general enrollment periods from January 1 to March 31 of each year. If you choose to enroll this way, coverage becomes effective on the first of July of the same year.
What Policy Option Did CBO Analyze? The option that CBO analyzed would raise the age of eligibility for Medicare by two months every year, beginning with people who were born in 1951 (who will turn 65 in 2016), until the eligibility age reached 67 for people born in 1962 (who will turn 67 in 2029). Thereafter, the eligibility age would remain at 67.
